However,

now I've said 'royal', I've begun to doubt myself.

On this chart, I'd plump for "blue".

I think.

not sure lapis lazuli is the correct shade !

@30pics4jackiesdiamond oooh, no!

[Casablanca]

I quite like Dodger Blue

[Annie-Sue]

@casablanca but what is Dodger Blue - and why???

[Casablanca]

@anniesue “ Dodger blue is a rich bright tone of the color azure named for its use in the uniform of the Los Angeles Dodgers.” Baseball team apparently. Who knew?!

[Annie-Sue]

@casablanca well we both do now! ;-))

I thought dodger blue had something to do with the artful dodger. 🤷🏻‍♀️
